Hi Waldemar!

Have you tried to add --with-sysroot/--with-build-sysroot while
configuring gcc? I normally use it on the host to build a
relocatable cross-compiler, but I think it might be a solution for
non-standard location, too.
I just tried it, it doesn't help:
root@unknown:/tmp/home/root# gcc hello.c
-I/opt/include
/tmp/cc2Z3b02.o: In function `main':
hello.c:(.text+0x44): undefined reference to `atexit'
collect2: error: ld returned 1 exit status
(after setting --with-sysroot option,
gcc requires '-I/opt/include' flag)
For further debugging you could strace -f -e open -o
log to see
if still something in /lib is opened while linking.
It doesn't seem to use anything beyond '/opt/...' (used the sed
expression to get rid of those '/../'): see log.txt.
Anything else I can try?
Thank you!
